This map shows thermal emission from erupting volcanoes on Io. The larger the spot, the larger the thermal emission.

Io boasts more than 130 active volcanoes with an estimated 400 total, making it the most volcanically active place in the Solar System. Juno used its Jovian Infrared Aurora Mapper (JIRAM) to take spectacular photographs of Io during Perijove 7 last July...
Juno’s Io looks like it’s on fire. Because JIRAM sees in infrared, a form of light we sense as heat, it picked up the signatures of at least 60 hot spots on the little moon on both the sunlight side (right) and the shadowed half. Like all missions to the planets, Juno’s cameras take pictures in black and white through a variety of color filters. The filtered views are later combined later by computers on the ground to create color pictures. Our featured image of Io was created by amateur astronomer and image processor Roman Tkachenko, who stacked raw images from this data set to create the vibrant view.
Io’s hotter than heck with erupting volcano temperatures as high as 2,400° F (1,300° C). Most of its lavas are made of basalt, a common type of volcanic rock found on Earth, but some flows consist of sulfur and sulfur dioxide, which paints the scabby landscape in unique colors.

Ping. Perhaps Io is ready for a massive discharge.
with our sire comply, nor break the sacred union of the sky: Lest, roused to rage, he shake the bless'd abodes, Launch the red lightning, and dethrone the gods. If you submit, the thunderer stands appeased; The gracious power is willing to be pleased.

Thanks BenLurkin.
Of course Juno would turn an unfriendly gaze on Io. Juno is Jupiter’s legal wife, while Io is just a heifer claiming to have had a one-night stand with Jupiter. Never believe a heifer when there is money involved.
Excellent
